TILE -MACHINE Specification of Letters Patent.

Patented July 21, 1908.

Application filed October 8, 1907. Serial No. 396,362.

To all whom it may concern:

Be it known that 1, CHARLES L. BALDWIN, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Tile Vlachines, of which the following is a specification.

My invention relates to improvements in tile-machines, and the object of my improvement is to provide mechanism for forming hollow cylindrical tile from cement, or a mixture of cement and other materials. This object I have accomplished by the mechanism which is hereinafter described and claimed, and which is illustrated in the accompanying drawings, in which,

Figure 1 is a side elevation of said ma chine, Fig. 2 is a front elevation of said machine, Fig. 3 is an enlarged detail perspective view of the shaping device for forming the interior periphery of a tile, Fig. 4 is a plan view of the rotatable carriage for the tile molds.

Similar numbers refer to similar parts throughout the several views.

My improved shaping device for forming the inner periphery of a tile consists of a plurality of solid cylinders 1, having square axial bosses 6 at each end, adapted to fit removably in sockets in the cross-bar 3 and the disk 2. The cross-bar 3 and disk 2 have central openings to receive the lower portion of the shaft 5, the part 4 of said shaft being squared to provide shoulders to space the said cross-bar and disk apart, and the diminished lower end S of the shaft being threaded to receive a lock-nut 7. The bosses 6 may have any desired plurality of sides, it being the intention to have each cylinder 1 adapted to be rotated through the space of a few degrees at a time to furnish a fresh outer surface when impairment has been occasioned there by wear.

The shaft 5 is made rotatable by the following described mechanism. The drivingbelt-wheel 42 is fixed on a shaft 41 rotatably mounted in bearings 38, 43 and 53 on the frame of the machine. The forward end of this shaft carries a bevel-pinion 54 in mesh with a bevel-gear-wheel on the upper end of the shaft 5, the latter being rotatably mounted in the bearing 58 supported by the machine frame.

The numeral 14 designates a cylindrical sleeve adapted to slide u on the pillar 16, the latter having stops 17 to imit the sleeves upward movement. A plurality of bracketed circular rings 11 having flanges 10 extend horizontally from the sleeve 14 to receive thereon the removable hollow cylindrical outer mold-casings 9. The inside of each ring 11 fits over the outside edge of the disk 2' to prevent leakage of material therebetween, but the inside surface of each casing 9 is spaced away from the cylinders 1 to a distance equal to the thickness of the tile to be formed therebetween.

The sleeve 14, rings 11, and casings 9 are rotated about the pillar 16 as follows: Supported on a projecting foot 30 of the pillar 16 resting on the base 34 is a bevel-gear-wheel 29 in mesh with a bevel-pinion 31 on the front end of a shaft 33 rotatably mounted in bearings 32 and 36. The shaft 33 has a beltwheel 35 driven by a belt 39 from a beltwheel 40 on the drive-shaft 41. The sleeve 14 has cogs 15 on its lower edge, while there is one upstanding cog or tooth 28 only on the upper surface of the bevel-gear-wheel 29, adapted to enter between any two of the teeth 15, when the sleeve is lowered to its lowest position. When the cog 28 is en gaged with the teeth 15, the sleeve is rotated to the extent of ninety degrees before it is elevated out of engagement by the following described mechanism.

Secured to the drive-shaft 41 is a pinion 44 in mesh with a gear-Wheel 45, the latter being secured on a short shaft 50 whose ends are rotatably mounted in bearings 51 and 52 011 the machine frame. The latter shaft has a pinion 46 thereon in mesh with a gear-wheel 47 on a stub-shaft 37 projecting rearwardly from a bearing 61 also supported by the machine frame. A intle bearing a roller 49 projects rearward y from the gear-wheel 47, and said roller is received Within a horizontal slot in a frame 57 to move in rolling contact between its horizontal bars 48 and 56. The frame 57 is fixed to the upper end of an up right or standard 60 whose lower end is secured to a bracket 59 extending laterally from a ring 62 loose about and kept up by studs 63 on the sleeve 14. When the gearwheel 47 is rotated by the means above de scribed, the roller 49 is caused to roll in the slot of said frame in one direction to the extent of one half of its length While said gearwheel is making one half of its revolution the frame'and sleeve 14 being thereby either moved down or up to its lowermost or uppermost limit of travel, but when the gearwheel 47 enters upon its next quarter revo' lution, the roller 49 reverses its position, and the frame and sleeve are also moved in the reverse direction. This vertical reciprocation of the sleeve 14 causes the outer casing 9 to move downward about the rotating disk 2 withits superincumbent cylinders 1, until said casing is entirely, clear from said disk at the lowermost position, at which point the ring 11 is moved about the pillar 16 one quarter of a revolution by the means hereinbefore described. Since the sleeve 14 is closely fitted about the pillar 16, its frictional contact therewith suffices to stop its rotation at any point where it is left in disengagement with the wheel 29. The cog 28 remains in operative engagement with the cogs 15 on the sleeve 14 long enough before being disengaged, to cause the said sleeve to revolve to the amount of a one quarter revolution, which shifts the mold-casing to one side. and brings another base-ring in place under the former-head. The casing with the newly formed tile therein may then be removed from the ring. Before removing said casing and while it is still descending, the upper flanged ring 27 which rests thereon and is designed to hold the casing in place and guide the material while being deposited therein, is elevated to clear the casing by the following means. Said ring 27 is supported on pintles 23 pivoted in the forward ends of levers 22, the latter being centrally pivoted on studs 21 to one of the lugs 13 on the ring 62. The rear members of said levers are bent obliquely downward and their ends are connected to springs 18 whose other ends are secured to other lugs 13 on said ring 62. A slide-rod 25 has its lower forked ends pivoted on studs 24 to said levers anterior to the fulcrums 21, while the upper portion of said rod is slidable through a vertical 0 ening in the forwardly projecting portion of the machine frame and is supplied at its upper end with a stop-piece 26 adapted to contact with the upper surface of said frame. The springs 18 ordinarily tend to keep the ring 27 in contact with the upper edge of the casing 9, but when the sleeve 14 has moved to nearly its lowermost position the stop 26 on the rod 25 contacts with the top of the frame, and prevents said ring following the casing, thus clearing it therefrom to permit of the casing s removal when at its lowermost position.

.When another casing is rotated thereunder,

and elevated, its upper edge contacts with the ring 27 and carries it up to its uppermost position. The cylinders 1, in practice, rotate within the casing 9, and, as the latter descends, compress and rub a tile into form between them from the material deposited therein between.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a tile machine, in'combination, an outer mold-casing, arotatable shaft, and a rotatable former insaid casing detachably secured to said shaft, said former being.com-- posed of a plurality of similarly formed bodies fixed with relation to each other but adapted to be shifted on their axes to present unworn surfaces to the material to be formed between them and said outer mold-casing.

2. In a tile machine, in combination, an outer mold-casing, a rotatable shaft having projecting arms, cylindrical bodies detachably secured to said arms and having their contact-surfaces spaced equally away from the inner surface of the mold-casing, the securing means between said bodies andsaid arms being adapted'to be shifted to partially rotate and adjust the said bodies to resent unworn portions of their contact sur aces to the material to be formed between them and said mold-casing.

3. In a tile machine, in combination, an

outer mold-casing, a former therein secured I about a rotatable shaft, and spaced away from said casing, a rotatable shaft, said former being composed of a plurality of cylinders with axes parallel to the axis of said mold-casing, and means for imparting to said casing a vertical reciprocatory movement about said former.

4. In a tile machine, in combination, an outer mold-casing, means for imparting to said mold-casing a limitedvertical recipr0- catory movement, a movable support for said mold-casing, means for shifting the horizontal position of said support, a rotatable shaft, and a former in said casing and spaced away therefrom, said former composed of a plurality of vertical cylinders detachably secured to said shaft and separated from each other, and means for changing the position of the wearing portions of the curved periphery of said cylinders relative to the inner shaft and separated from each other, means for imparting to said mold-easing a vertical reciprocatory movement about and away from said former, means for changing the position of the wearing portions of the curved periphery of said cylinders relative to the inner surface of said mold-easing, and a reci rocatory hopper-ring adapted to ordinaril y removably contact with the upper edge of said mold-casing but lift therefrom when the 10 casing has nearly arrived at its lowermost position.
